That is AWESOME.
Something you should also consider are vent shades. That way you can keep your windows open at night and not worry about rain coming in. In fact, I think I have a spare set of front vents. If you want them, they're yours
You can fit a full size air mattress as well, easy to pack and store instead of a full size mattress.
Your frame idea is such a good idea.
Thanks for the offer on the vent shades I have a set coming for mine I agree they work great for letting in air without the rain. I had a inflatable but I can't seem to get one to last more than a couple years we also have a tempurpedic for our bed so having a 5 inch one works well in the rig and I store it on our guest bed.. We may even use the foam one for big tent camping too.
I have a few more things in the works for it and will post up photos as I get them done.. Working on some accent paint work on the hood and sides , blacking out the reflectec, a custom built roof rack and a rear spare tire rack.
